A few years ago, I tried out a Rivera amp which was connected to a Los Lobottom. It sounded frikken fabulous, but was hella expensive and way outta my league. They don't make 'em anymore, but I'm considering building a 2x12 300 watt powered sub with a volume and crossover frequency control, in a sealed box to fit under my 4x12 cab. Is anyone out there using a sub in their guitar rig that can give me a few ideas as to whether or not this is a worthwhile endeavour? Or if anyone else thinks this is an awesome idea, do you want to get together and build them?

I've heard of a few guitarists using subs in their rig, and most say that they couldn't live without them now. Expect to re-EQ your tone, particularly if you run a bass-heavy amp like a Mesa.

The only actual guitar sub I know of besides the Rivera is the ISP Technologies Vector SL. Not cheap, but definitely drool-worthy.

Holy schnapps, that's pricey. I reckon I can build one for less than 1/2 that. I'll let you know how it turns out. If I fail, I think it'll still work in someone's car.

Randall makes a 15 inch guitar cab

i play through a logitech sound system with a sub and it adds a lotta heavy bass, i love it

I hate to say there is no Santa, but I find this a bad idea.

Low E on a guitar is 82Hz. There is only mud below that will interfere with the bass.

Most mixers will cut all the sub low on a guitar to make room in the mix . Sometimes it is cut quite high, especially in metal to make these super clean mixes. A Marshal with a 4x12 makes too much low end for the stage I find. That is why I was forced to buy an Ampeg SVT.

Maybe this will sound good to you but it will create problems on stage and for the mixer.

Leave the bass to the bass player... they need something to make them feel useful

yeah, it looks like it will sound cool to me, but will walk all over the bassist's frequencies. if we ever find one. bassists? anywhere?

Compound Terror from Victoria have 1 guitarist and no bass player. He plays 8 strings and uses 2 separate half stacks. For awhile he was using a Vader 4x12 cab with one head and a Vader 2x15 cab with another head, but last time I saw them he'd swapped one of thne Vader cabs (I don't know which one) for an Orange.

...then after finding a less traditional sound person or a basement DIY gig with a vocal-only PA you can use a 10-band or bass eq (or a DOD Meatbox and push out 30hz)
